Kehoe Marine Construction specializes in heavy civil dredging services for marinas, harbours, and ship slips to ensure waterways remain open, accessible, and safe for all types of vessels. With years of experience and a dedicated team of professionals, we use state-of-the-art equipment and environmentally responsible practices to meet the needs of our clients while protecting the surrounding environment.

​

Surveying and Pre-Dredge Assessment

Before any dredging project begins, we conduct detailed bathymetric surveys and sediment sampling to assess the current condition of the waterway. Our team uses advanced sonar and GPS technology to create precise maps of the underwater topography, ensuring accurate project planning and execution. Through thorough analysis, we identify sediment composition, depth requirements, and any potential environmental concerns.

​

Dredging Methods

Kehoe Marine employs a variety of dredging methods tailored to the specific needs of each project:

​

Mechanical Dredging – Ideal for compact and dense materials, this method uses clamshell or bucket dredgers to excavate sediment efficiently.

​

Rock Removal – Utilizes hydraulic hoe rams to effectively break rock on lake bottom and remove mechanically with dredge.

​

Environmental Dredging – For sensitive sites, we use precision dredging techniques to minimize turbidity and reduce environmental impact.

​

Each method is carefully selected based on the project’s scope, sediment type, and environmental factors to ensure maximum efficiency and minimal disturbance.

​

Disposal and Sediment Management

Proper disposal of dredged material is a critical part of any project. Kehoe Marine offers multiple disposal options depending on the type and condition of the sediment:

​

Open-Water Disposal – For clean sediments that meet environmental standards, we transport the material to approved open-water disposal sites.

​

On-land Disposal – When appropriate, we transfer material to designated upland sites for reuse or safe storage.

Our team works closely with regulatory authorities to ensure all disposal activities comply with local, provincial, and federal regulations.

​

Handling Contaminated Sediments

Kehoe Marine has extensive experience managing projects involving contaminated sediments. We follow strict environmental protocols to ensure that hazardous and non-hazardous materials are handled, transported, and disposed of in compliance with environmental regulations. Our team utilizes specialized dredging techniques to minimize the spread of contaminants and partners with certified disposal facilities to ensure proper treatment and containment.

​

Our proactive approach ensures that all contaminated materials are managed responsibly, reducing the risk to aquatic ecosystems and surrounding communities.

​

Commitment to Environmental Responsibility

Kehoe Marine is dedicated to maintaining the delicate balance between industrial operations and environmental protection. We employ best practices to minimize environmental disruption, monitor water quality throughout the dredging process, and implement mitigation measures where necessary. Our team is committed to sustainable dredging practices that support the long-term health of waterways and marine ecosystems.
